Use materialized views in the default-sql template (#1709) 

## Changes

Materialized views now support `CREATE OR REPLACE`
([docs](https://docs.databricks.com/en/sql/language-manual/sql-ref-syntax-ddl-create-materialized-view.html))!
This makes it possible to use them with Workflows in DABs.This PR
updates the template to use a materialized view rather than a regular
view.

## Tests

Manually validated in production.
